Discussion Overview

The discussion centers around building a trebuchet, specifically focusing on the design and optimization of the sling. Participants share their experiences and seek advice on various aspects of trebuchet construction, including sling length, release mechanisms, and structural integrity.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Experimental/applied

Main Points Raised

  • One participant asks for specific advice regarding the sling for their 7-foot tall trebuchet with a 12-foot arm.
  • Another participant inquires about the specific information the original poster is seeking.
  • It is suggested that the sling length should typically match the length of the arm.
  • A participant questions whether the original poster has determined the sling length yet.
  • A contributor shares insights from their experience, emphasizing the importance of the sling release mechanism and structural integrity of the trebuchet.
  • They recommend a website that includes a computer program for modeling trebuchets and determining optimal sling lengths.

Areas of Agreement / Disagreement

Participants have not reached a consensus on the optimal sling length or the best release mechanism, and multiple viewpoints are presented regarding these aspects of trebuchet design.

Contextual Notes

Participants have not provided specific definitions for terms like "sling length" or "release mechanism," and there are assumptions regarding the materials used in construction that remain unaddressed.

Who May Find This Useful

Individuals interested in building trebuchets, those seeking practical advice on mechanical design, and enthusiasts of experimental physics may find this discussion beneficial.

hey all,
im building a trebuchet and i wanted a litte advice on slings. my trebuchet is about 7 feet tall with a 12 foot arm; i wanted to know if anyone had experience in trebuchets and if they could help me with the sling, or direct me to somewhere with that info. thanks

what exactly do you want to know?

usually the length of the sling is about the same length as the arm. do you know how to set up a trigger?
 
Sling Length

Did you ever get your sling length figured out?
 
A program to help you out

Nice start you got there. Having been involved in two trebuchet projects (my brother did the work, I just advised on the physics parts), I noticed three things are important.

1) The sling release mechanism: A ring that slides off a bent nail is easy and works well. The angle of the bent nail matters.

2) Structural integrity: From your picture, if that's only a 2x4 on the arm... how much weight are you planning on putting in the box? Also, what is that pivot beam made of?

3) Weight and length ratios: Check out the website below for optimal parameters.


This website, http://www.algobeautytreb.com/" , is by far the best site I've found. It even includes a computer program to model your trebuchet and help you figure out the optimal sling length. Very helpful.
